SPECIFICATION forming part of Letters Patent N0.388,04'7, dated August 2, i838.

(No modeLl To @ZZ whom it rim/y concern:

Be it known that we, lvnn JOHNSON and OLAUs Hanson, beth of Worcester, in the county of \Vorcestcr and State of llassachnsetts, haveinventcd certain new and useful Iniprovenienis in Velocipedes; and we do hereby declare that the following is a full, clear, and exact description ol' the same, reference being had to the accompanying drawings, forming a part of this specilication, and in which- Figure l represents so much ol a bicycle as is necessary to illustrate our aforesaid improvements. Fig. 2 is n cross-section online a, Fig. 1, through the handle-bnr, showing beyond a side view ofthe paris illustrated in Fig. l, also showing a part et' the main or driving Wheel. Fig. 3 rcpiesenis,npon an enlarged scale,a top or plan view of the bicyclehead and a part of the hahdle-bar. All the ligures following are also upon the saine enlarged scale. Fig. 4 is a vertical transverse section through the head and handlesbar, laken on line I), Fig. 3, look` ing in the direction indicated by the arrow, same figure. Fig. 5 also represents a vertical transverse section with the center bolt and all fastening-s removed, with the handle-bar in position, its cap detached, and said cap shown above the saine in position preparatory to ttingv it over the hnndlebar and head; and Figs. 6 and 7 nre vertical transverse and longitudinal sections taken attire points indicated by lines b and o, respectively, Fig. 3, showing modiiications in the construction hereinafter described.

Our invention relates to the handle-bar attachnient and brake mechanism oia veloci pede, and is designed more especially for use on bicycles.

It consists in an improved means of adjustably fastening the handlebar to the head and of imparting a yielding pressure to the brake below its pivot to keep it elevated above the wheel, as hereinafter more full y set forth.

In order llint others may better understand our aforesaid improvements, we will new proceed to describe the saine more in detail, with reference to the aecoinpan ying drawings.

The part marked A represents the velocipedehead; B, the central portion of thefhanl dle-bar; C, part of the backbone; D, part of the main or driving Wheel, and E the brake, having the nsnal foot. d, and hinged at e to the bearing f, extending forward from the head, also provided with the spring y below its pivot, and engaging at its upper end with 5 the usual bralrelever, F, as hereinafter more fully described.

Our improvement in the handlefbar attachment consists ofthe following construction and arrangement of parts: A bearing, G, is formed 6 upon the front side of the upper end of thc head, which projects forward and laterally therefrom and is provided with a horizontal trough er groove, h, in the forni of a half-cirele, to receive the lower half of the handle-bar. It is also provided with a cap, i', having a reverse trough or groove, h', so to nt over the upper half of said handlebar and hold it in position in its bearing. Suid cap i is in turn held in a secure and rigid position after adjnstrnent by means of the screw-boltsjj, passing through the cap, the handle-bar, and into the bearing, and by forming a llange, t', on the cap, extending back from its upper part, so as to come under the Washer Z and lock-nut m, of 7 the usual adjustable center bolt, n, said flange k being made upon its back edge to conform to the shape ofthe bolt, as indicated by dotted lines in Fig. 3. By thus constructing the cap it is obvious that by turning down the locknnt, as is usual in locking the center bolt in position after adjustment, the cap, as Well as said center bolt, is fastened under said nut, and, being also fastened by means ofthe usual bolts, jj, as above described, the handlebar is held in avery secure and rigid manner from both rotary and longitudinal inoveinents,while at the same time it may be detached in an easy and expeditious manner. Additional strength may be imparted to the fastening by forming projections o o upon the under side of the iiange 7c and correspondingly-shaped openings or slots p p to receive them in the head A, and also by extending said ilange L clear across the top of the head, with a vertical opening therein to receive the center bolt, as shown in Fig. 6. In making our improved fastening the horizontal joints l bet-Ween the cap and the head and its bearing are preferably made a little open, as indicated by heavy lines in 10o the drawings, so as to obtain a tight tit of the circular groove in the cap against the handlebar, also to admit of taking up the wear incident to usage, and thus maintaining said tight fit against the handle-bar.

The washer under the lock-nut m may be used or not, as desired, it being inessential to the carrying out of our invention.

The only feature which we claim, broadly, as new in the handle-bar attachment is extending the cap t' under the lock-nut of the center bolt, so as to utilize the holding-power thereof, in connection with the usual l'astenings.

We make no claim, broadly, to the combination of the head having a bearing for the handle-bar, said handle-bar, and the fasteningbolts j, the same being, as we are aware, already covered by several patents.

As the construction of the flange k and the iitting thereof' between theloek-nut and head is susceptible of considerable variation, We reserve the right to modify the same as occasion requires. We also reserve the right to combine with our improvementahandle-bar made hollow, solid, having asleeve, 1", thereon, as shown in Figs?, or in any other suitable and convenient manner.

Our improvement in the brake mechanism consists simply in forming a horizontal opening or socket in the back side of the brake E, just below its pivot c, and fitting therein the spiral spring g, previously referred to. The outer end of said spring is arranged to bear Vagainst the side of the head A, and thus produces a constant yielding pressure against the lower part of said brake to keep its foot d in an elevated position above the wheel, as shown in Fig. 2. Said spring device, as will at once be seen, serves its purpose effcctually, while at the same time being both simple and durable.

We are aware of the English Patent No. 562 of 1882, for improvement in velocipedes, in which a detachable cap is shown over the handle-bar, having a horizontal projection fitted overavertical stem ou the head, and fastened, in addition, tothe lock-nut by screws passed through the front edges of the cap and bearing outside ofthe handle-bar. Therefore, in view of said patent, we make no claim to the flange k, broadly, but limit our invention to the specic construction set forth and shown in our specification and drawings.

vVe are also aware of the United States patent to S. Martin, No. 339,446, dated April G, 1886, which shows a stud, r2, ou the under side of the handle-bar engaging with a hole, q, in the bracket,77 corresponding to bearing G, for the purpose of holding said handle-bar from rotary and longitudinal Inovenient, and make no claim thereto.

The fastening-bolts j, hereinbefore described, not only serve the purpose of holding the handle-bar proper, but also assist in holding the cap t in position over said handle-bar, and thus greatly strengthen the fastening to an extent not attainable by the above patented construction.

Having described our aforesaid improvements, what we claim as new, and desire to se- Y cure by Letters Patent, is-

1. In a veloeipede, the head A, having the bearing G, made, substantially as described, to receive the handle-bar, said bearing in turn having suitable threaded openings to receive the fastening-boltsj, the usual center bolt, n, and the lock -nut m, preferably having a washer, l, under the same, in combination with the detachable cap fr?, also having suitable openings to receive the aforesaid fastening-boltsj and adapted to fit over the handlebar and bearing G, also having a horizontal flange, It, extending back therefrom over the head, said flange being provided with a vertical slot or opening to receive the center bolt,

the handle-bar having transverse openings through the same corresponding to those in the bearing and cap for the same purpose, and the lfastening-bolts j, said boltsj serving the double purpose of holding the forward part of cap i, as well as the handle-bar, from rotary and longitudinal movement, substantially as set forth.

2. In a velocipede, the head A, having the bearing G, made, substantially as described, to receive the handle-bar, and the slots or openings p, to receive the projections o'o'ii the cap t, said bearing also having suitable openings to receive the fastening-boltsj, the center bolt, n, and lock-nut m, preferably having a washer, Z, under the same, in combination with the detachable cap t, adapted to fit over the bearing G and handle-bar, and having a horizontal flange, k, extending back therefrom over the head, also having the projections 0 upon the under side thereof, and snit- IOO able openings to receive bolts j, said flange k I also having avertical slot or opening to receive the center bolt, the handle-bar having transverse openings through the same corresponding to those in the bearing and cap for the same purpose, and the fastening-boltsj, substantially as and for the purpose set forth.

3. The velocipede-brake E, having a horizontal opening or socket in the back side thereof below its pivot, in combination with the spring g, vfitted therein, and the head A, substantially as and for the purpose set forth.
